Fast space-variant elliptical filtering using box splines [PDF]
, 2011 The efficient realization of linear space-variant (non-convolution) filters is a challenging computational problem in image processing. In this paper, we demonstrate that it is possible to filter an image with a Gaussian-like elliptic window of varying ...

Preparation and measurement: two independent sources of uncertainty in quantum mechanics [PDF]
, 1999 In the Copenhagen interpretation the Heisenberg uncertainty relation is interpreted as the mathematical expression of the concept of complementarity, quantifying the mutual disturbance necessarily taking place in a simultaneous or joint measurement of ...

Coagulation and fragmentation processes with evolving size and shape profiles : a semigroup approach [PDF]
, 2013 We investigate a class of bivariate coagulation-fragmentation equations. These equations describe the evolution of a system of particles that are characterised not only by a discrete size variable but also by a shape variable which can be either discrete

Some generalized bivariate Bernstein operators [PDF]
Miskolc Mathematical Notes, 2000 If \(q>0\) and \(i\in\{0,1,\dots\}\) then \([i]=(1-q^i)(1-q)^{-1}\) for \(q\neq 1\) and \([i]=i\) for \(q=1\), \([i]!=[i][i-1]\dots[1]\) for \(i\in \mathbb{N}\) and \([i]!=1\) for \(i=0\), \(\left[\begin{matrix} k \\ r\end{matrix}\right]=\left([k]!\right)\left([r]![k-r]!\right)^{-1}\).

Order-Degree Curves for Hypergeometric Creative Telescoping
, 2012 Creative telescoping applied to a bivariate proper hypergeometric term produces linear recurrence operators with polynomial coefficients, called telescopers. We provide bounds for the degrees of the polynomials appearing in these operators.

The Haroche-Ramsey experiment as a generalized measurement [PDF]
, 2000 A number of atomic beam experiments, related to the Ramsey experiment and a recent experiment by Brune et al., are studied with respect to the question of complementarity.

Reconfigurable Three‐Dimensional Superconducting Nanoarchitectures
Advanced Functional Materials, EarlyView.3D superconducting nanostructures offer new possibilities for emergent physical phenomena. However, fabricating complex geometries remains challenging. Here 3D nanoprinting of complex 3D superconducting nanoarchitectures is established. As well as propagating superconducting vortices in 3D, anisotropic superconducting properties with geometric ...

Solving Dynamic Discrete Choice Models Using Smoothing and Sieve Methods [PDF]
, 2019 We propose to combine smoothing, simulations and sieve approximations to solve for either the integrated or expected value function in a general class of dynamic discrete choice (DDC) models.

β‐Adrenergic Signaling Promotes Anti‐Tumor Immunity in TP53‐mutant Oral Squamous Cell Carcinoma
Advanced Science, EarlyView.β‐adrenergic stimulation enhances anti‐tumor immunity in TP53‐deficient oral squamous cell carcinoma by inducing tumor‐derived secretion of CXCL10, which attracts and activates cytotoxic CD8+ T cells. The findings demonstrate that β‐adrenergic signaling alters tumor–immune interactions via CXCL10‐mediated paracrine activation, revealing a neuro‐immune ...
